Super powers in a boxfight

I can’t figure out how to make the super powers in box fight

What powers do you need?

Could you give me context on what a box fight is? Like fortnite?

You could do like extra damage, extra speed, or special gadgets for a couple of seconds.

I have the powers I want like flash and juggernaut but I can’t figure out the devices

Juggernaut, well it depends if you have healing items in your game.

Make it so there’s a button that gives speed, and make it so only the player that chose it can use it.

Juggernaut basically, just give them extra health if you don’t have healing items in your game.

for flash, use he speed modifier

I need help because you can’t just use the speed moniker and put it on a spawn pap
